Unlocking the full roster allows you to: Practice high-difficulty levels like "Finding the Bomb." Replay iconic missions like "Eagle's Nest" or "Trainyard."
Skip technical glitches that might prevent progress on modern systems. Method 1: The "Everything" Cheat (Easiest Way)
The most reliable way to unlock everything instantly is by using the built-in developer cheat code. This works on almost all versions of the game, including the GOG and Steam (via wrappers) versions. Launch Project IGI. Stay on the Main Menu screen.
Type nada slowly on your keyboard. (You won’t see a text box; just type it).
Now, you can select any mission from the mission select screen.
Note: If "nada" doesn't work, try typing it during the intro cinematic or while in the mission select menu itself. Method 2: The Config File Hack Project IGI 1: How to Unlock All Missions
If you want a permanent unlock that doesn't require typing a code every time you launch the game, you can modify the game's internal files.
Go to your Project IGI installation folder (usually C:\Program Files (x86)\Innerloop\Project IGI). Open the pc folder.
Look for a file named MISSION.CFG (or similar configuration files depending on your patch version). Open it with Notepad. Look for lines labeled Mission 1, Mission 2, etc.
Change the status or "unlocked" value from 0 to 1 for all missions. Save and Close. Method 3: Using a 100% Save File
If you don't want to mess with codes or configs, you can download a "100% Completed" save file from community hubs like ModDB or IGI fan sites.
Download the save.dat or profile folder from a trusted source.
Replace the existing save files in your IGI/save or IGI/pc/save directory. Restart the game, and all medals/missions will be visible. Project IGI Mission List
